ADJUSTABLE MOLDING STRIP.

Application filed my 14, 1927. Serial No. 205,587.

' square head is slightly less than the width of the slot 11 formed in the frame board 10 and the widths of the ledges 16 are of the same dimension, while the distance between the edge of one ledge to the edge of the opposite ledge is slightly less than the length of the slot 11, so that the ledge and square end of the bolt may be passed through the slot 11 from one side of the board. The threaded ends of the bolts are adapted to The main object of this invention is'to provide a molding strip which may be used on windows or doors and its construction is such that it will permit transverse shifting of the strip to permit it to beadjustedto various positions to take up for space whlch would occur when the molding strip shrinks or is otherwise deformed.

Another object of this invention is to provide a molding strip which is adjustably mounted upon the frame of a windowor door and is transversely movable across the frame of the window or door for the purpose of compensating for shrinkage, warpage and other defects common in the usage of such doors and windows.

The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a perspective view of a portion of a door or window frame showing the adjustable molding strip mounted in place thereon.

Figure 2 is a front elevational view of a section of a door or window frame showing the molding strip, partly broken away at one portion, mounted thereon.

Figure 3 is a side elevational view of Figno ure 2 showing a portion of the molding strip and frame broken away to illustrate the construction thereof.

Figure 4 is a cross sectional View taken on line 4-4 of Figure 3.

Figure 5 is a perspective view of the bolt used with the adjustable molding strip.

Referring in detail to the drawing, the numeral indicates the upright board on one side of a door or window and forms part of the frame of the door or window. At spaced apart positions on this board, a plurality of straight slots 11 are formed; These slots extend transversely across said board and are adapted to be entirely coircealed by the molding strip 12. The frame of the door or window is preferably of hollow construction and the slots 11 in the 10 and serve as strips 12.

The molding strip 12 may be of continuous length or of shorter lengths arranged end to end in a: butt or lap joint. The molding strips are of hollow construction being provided with an inner concealed channel 17 which is surrounded by side walls 18 and 19 and a roof 20, the remaining side being opened. Secured in the channels, at distances spaced apart from each other equal to distances between the slots 11, blocks 21 are located. These blocks are securely fixed to the walls and roof of the molding strip through any desirable means and are provided with openings. These openings pass thru the blocks and the roof of the molding strip and receive the threaded ends 13 of the bolts. The exposed face of the roof 20 has conical seats which surround the openings, receiving the bolts and has conical threaded washers 22 seated thereon, the galshers engaging the threaded ends of the The molding strip illustrated herein is adapted to compensate or take up for whatever shrinkage occurs in the building materials used, which is ordinarily wood. If a space between molding strips and doors were to be created thru shrinkage or warpage an unnecessary strain would occur on the hinges of the door and in the caseof windows the same would not be weatherproof and would rattle in the wind. To eliminate the necessity of pulling nails or screws from a permanently mounted molding board are adapted to receive securem nt strip to shift the same, this invention has b lt Th se bolts comprise a shank 13 cirbeen conceived. The bolt is slidable in the cular in cross section and threaded at one slot and after slightly loosening the threaded end as indicated by the numeral 14. The washers 22 the entire molding strip may be end of the bolt opposite to the threaded end shifted transversely the length of the slot is provided with a square head 15 and is sur- 11 from one side to the other. Only slight mounted by ledges 16 which project in opposhifting of the moldlng strips is necessary site directions from the top of the square as the degree ofshrinkage or warpage of head. The distance between the flats of the the said strips is never great. After the anchors for the molding project outwardly from the face of the board moldingstrip has been shifted to its new position the Washer 22 is again tightened thereby releasably securing said molding strip in place in its new position on the frame or end of the door or WillClOW.

It is to he noted that certain changes in form and construction may he made Without departing from thespirit and scope of the invention.

securing said molding strips adjustahly in position within the limits of said slots.

2. In combination with a frame board of a door or window said board having spaced apart slots therein extending transversely, a channel molding strip covering said slots, block s secured :Within said molding strips,

esayma bolts slidahle and non-rotatable in said slots engaging the molding strips for anchoring the SHIDGLQ conical Washer engaging said bolt, said Washer when t ghtened on said bolt releasably securing the molding strip in any desired position.

i 3; Incomhination with a frame board of a door or Window said board having spaced apart slots therein extending transversely, a channel molding strip covering said slots, blocks secured Within said molding strips, bolts slidable and nonrotatahle in said slots engaging the molding strips for anchorings, thesame, a conical washer engaging said bolt, said washer when tightened onsaid bolt releasahly securing the molding strip in any desired position, said bolt having a circular threaded shank, a square headon said shank and ledges surniounting said square head, the ledges forn'iing a stop shoulder and the square head permitting sliding of the bolt in said slots but nonrotatahle thereof. p p
